I too have been having lockups and have posted here, with Penguin,
and with the redhat-list.

The machines are 2 Penguin dual PIII (network or load related),
and a Dell WS400 dual PII/300 (sound active then access the floppy).

either.

not locked up at that time -- it locked up later....

Since I have 3 systems doing it, others have also reported similar,
I think it could be kernel related....
